Getting SNS Post Ideas with ChatGPT - AI Social Media Marketing Guide

Introduction

Do you lose track of time worrying about what to post on SNS every day? When I worked as a marketing manager, it was always a concern. What should I post today, what angle should I take, what photo should I use... It often took hours just to prepare one post.

Especially when managing multiple channels like Instagram, Facebook, and Naver Blog, content ideas run out quickly. So I'd get inspiration from competitor accounts, flip through marketing books, or brainstorm in team meetings. But now you don't have to do that!

AI can become your brainstorming partner. Just tell Claude or ChatGPT about your brand and target audience, and within minutes, they'll pour out a month's worth of content ideas. From various angles too.

Requesting SNS Content Ideas from AI

The key is giving AI enough information. If you vaguely ask "Give me Instagram ideas," you'll only get generic responses. But if you specifically tell it about brand characteristics, target customers, and product features, you can get customized ideas.

AI like Claude or ChatGPT has learned countless marketing cases, so they can suggest content strategies perfect for your brand. When I actually tested it, over 70% of the suggested ideas were immediately executable.

My Input:

We're an eco-friendly cosmetics brand targeting women in their 20s-30s.

Real Example 2: Monthly Content Calendar

My Input:

Based on the above ideas,
create a January Instagram content calendar.
Based on 3 posts per week.

Claude's Response:

💡 Usage Tips:

• Monday: Motivational/educational content
• Wednesday: Practical tips/routines
• Friday: Fun and light content/events

As you can see, AI doesn't just give ideas. It presents an executable plan considering specific posting dates, day-of-week strategy, and hashtags.

What I found particularly useful is that each content has a clear purpose. For example, January 6th's "Environmental Message" leverages the timeliness of New Year's resolutions, and January 20th's "DIY Tips" is placed before the weekend to give time to actually try it. Such thoughtful consideration multiplies content effectiveness.

Also, since Instagram is a visual platform, consider what images or videos would work well with each idea. Based on AI-suggested ideas, you can ask follow-up questions like "What visuals would suit this content?" to get even more specific guidance.

Real Example 3: Facebook Content Strategy

My Input:

Same brand, but should Facebook be different from Instagram?
Facebook target is 30-40s.

Claude's Response:

📘 Facebook vs Instagram Content Differentiation

Instagram (20-30s)

• Tone & Manner: Bright and cheerful, lots of emojis
• Content Length: Short and concise (1-2 lines)
• Visual: Sensory photos, filter usage
• Format: Actively use Stories, Reels
• Hashtags: Actively use 10-15

Facebook (30-40s)

• Tone & Manner: Reliable and professional
• Content Length: Detailed explanation (3-5+ lines)
• Visual: Information-centered, infographics
• Format: Long posts, link sharing, live broadcasts
• Hashtags: Selectively use 3-5

Facebook Post Example

Topic: Camellia oil ingredient introduction

Instagram Version:

Oil extracted from camellia flowers 💚
Secret of our hair essence!

✨ Shine UP
✨ Damage DOWN

#CamelliaOil #NaturalIngredients #HairCare #Shine #CleanBeauty

Facebook Version:

[Jeju Camellia Flower Oil, Why is it Good for Hair Care?]

The camellia tree is an evergreen tree native to Jeju,
and oil extracted from camellia seeds has been
a natural ingredient protecting women's hair since ancient times.

🌿 3 Benefits of Camellia Oil:

1. Omega-9 Fatty Acids (85% content)
   → Deep nutrition to hair
   → Improves dry and damaged hair

2. Vitamins E & A
   → Promotes scalp blood circulation
   → Prevents hair loss

3. Polyphenol Components
   → Antioxidant action
   → Recovers from coloring/perm damage

Our brand extracts oil only from
organically grown camellia trees in Jeju's pristine areas.

Experience the natural benefits
without chemical additives.

Differences:

• Instagram: Emotional, short and impactful
• Facebook: Logical, detailed information, educational

Even when introducing the same product and ingredient, you need to take a completely different approach depending on the platform. Instagram users quickly scroll looking for visually attractive content, so emotional messages that catch the eye work well.

On the other hand, Facebook users, especially those in their 30-40s, are more careful with purchase decisions. They want to know in detail why the product is good, what ingredients are in it, and what the scientific basis is. That's why depth of information is important on Facebook.

When I was consulting for a brand, posting the same content identically on Instagram and Facebook caused Facebook engagement to drop sharply. After switching to platform-specific content, Facebook engagement increased by over 60%. AI understands these platform-specific characteristics accurately and can suggest content optimized for each channel.

Making AI Ideas Your Own

Once you've received AI-suggested ideas, it's time to add your brand's unique color. While AI provides an excellent starting point, the final touch needs to be yours.

First, prioritize among the 10 ideas AI suggested. Not all ideas are equally good. It's important to select those that best match your brand philosophy and align with your current marketing goals.

Next, add your brand's unique tone and manner to each idea. For example, if you're an eco-friendly brand, emphasize environmental protection messages more, or if you're a young brand, add memes or trendy expressions that MZ generation likes.

The method I recommend is combining 3-4 ideas AI gave you to create something completely new. For example, combining "customer review" and "environmental message" ideas creates "authentic stories of customers using eco-friendly products," a more powerful piece of content. This way, you can create unique content completely differentiated from competitors.

Conclusion

Don't worry about SNS content ideas anymore. Ask AI and dozens of ideas will pour out. The important thing is refining those ideas to fit our brand colors and actually executing them!

At first, AI's suggestions might feel awkward. But after using it a few times, you'll get the hang of talking with AI and be able to receive increasingly accurate ideas. As your prompt writing skills improve, AI becomes an even more powerful tool.

In the next post, I'll show you how to hand over actual copywriting to AI, beyond just ideas. You'll see AI churning out everything from ad copy to SNS captions to email subject lines!

💡 Today's Tip: Don't use AI's ideas as-is - try combining 3-4 to create new ideas. You'll get more original results!
